to the axles or formed integral ably secured is secured a therewith. T 0 each bracket cushion as solid rubber, by means of a divided bolt, the members 16 and 17 of which are connected together by knuckle joint 18.

It will be noted onrefei'ring to Figure 5 that the head of the member 16 is locatedtallic casing in which the block 15 conare the members of the the free ends of tained. 22 and 23 s de spring suspension,

which bear upon the top of the casing 1 and are connected thereto in a manner hereinafter described.

2% is an inverted channel member fitting within each of the side members 3 and 4; ot the chassis frame centrally thereof. The'inner ends of the members 22 and 23 extend into the ends of the channel 2 1 and are secured therein by means of rivets 25.

It will be noted particularly on referring to Figure 3 that there is' an interspace between the top of the channel member 24 and the opposing portion of the corresponding side bar 3 or 4 so as to permit of a slight swinging movement within the side bar of the chassis frame as hereinafter described.

26 is a U-shaped strap secured within the channel member 2% centrally of its length and provided in the bottom thereof with a central orifice 27. 28 is a block which fits within the strap 26 and is provided with a downwardly extending stem 29 fitting within the orifice 27 so that the block 28 swings upon a vertical axis. 30 is a cross pin extending centrally through the block in a transverse direction and through the side walls of the members 3 and 1.

The ends of the spring members 22 and 23 as hereinbefore stated bear upon the top of the casing 21. The. spring members 22 and 23 are preferably formed with a double leaf as indicated in Figure 5. The lower leaf rests directly upon the casing21 and is rovided with orifices 22 and 23 through which the upper members of the bolts 19 and 20 extend, the bolts fitting such orifices. The

block 15*, of resilient material such upper leaf is provided with slotted or enlarged orifices 22 and 23 registering with the orifices 22 and 23* and through which the bolts 19 and 20 also extend,

31 is a retaining plate provided with orifices 81* and 31 through which the upper ends of the bolts 19 and 20 extend being secured by nuts 32 bearing upon the upper face of the plate 31.

It will thus be seen that when the tendency is for the springs 22 and 23 to spread and relax, that such movement is resisted or cush ioned by the bolts 19 and 20 embedded in the cushioned block 15*.

From this description it will be seen that I have devised a simple construction of spring suspension for chassis frames which will tend to reduce torsional strain in the frame, eliminate sag, oppose any tendency for the body to roll or pitch and which will provide a cushioned easy riding action which will be easy running and have the best riding qualities.

That I claim as my invention is 1. In a spring suspension device for automobiles, the combination With the front and rear axles, of a chassis frame, the members of which are inverted U-shaped in cross section, transverse suspension springs located at each end of the frame, means for supportingthe ends of the transverse springs upon evzeee the axles,,longitudinal suspension springs located in the side members of the frame, and connecting means between the ends of the spring and the front and rear axles in proximity to each end thereof.

2. In a spring suspension device for automobiles, the combination with the front and rear axles, chassis frame and spring supports at the end of the frame, of side suspen sion means comprising an inverted U-shaped channel member mounted centrally of its length within the side bars of the chassis frame to swing in a vertical plane, leaf springs secured at their ends Within the ends of the channel bar, and means for supporting the outer end of the spring upon the front and rear axles.

3. In a springsuspension device for automobiles, the combination with the front and rear axles, chassis frame' and spring supports at the end of the frame, of side suspension means comprisinga transverse pin extending through the side Walls of the side bars of the chassis frame, a block mounted thereon,-a channel bar mounted upon the block to swing, and leaf springs extending from each end of the channel bar and mount: ed at their free ends upon the front and rear axles.
